powermac S900 6 slot PCI broken in 2.6.16

[Robert Brose]

The s900 has a 6 slot PCI bus. It works fine in 2.6.15. In 2.6.16 it
appears the interrupts are being assigned in an incorrect way, I get
an interrupt assignment failure on the device on the 21052 bridge.
(notice in the interrupt assignment at the end that the stuff on the
bridge is on irq 25 when it works in 2.6.15 and irq 1 when it doesn't
work in 2.6.16).

2.6.16 relevant dmesg
irq: Found primary Apple PIC /bandit/gc for 32 irqs
irq: System has 32 possible interrupts
.
.
ohci_hcd 0000:01:03.0: Unlink after no-IRQ?  Controller is probably using the wrong IRQ.
